How to get the username of the current user logged in a Flask app running on an Apache server?
In a Flask app running on an Apache server, you can get the username of the current user using the REMOTE_USER
environment variable. The REMOTE_USER
variable is set by Apache when it performs HTTP basic authentication or other authentication mechanisms.
Here's how you can access the REMOTE_USER
variable in your Flask app:
pythonfrom flask import Flask, request
app = Flask(__name__)
@app.route('/')
def get_current_user():
username = request.environ.get('REMOTE_USER')
return f"Current User: {username}"
if __name__ == '__main__':
app.run()
In this example, we define a simple Flask route /
that returns the username of the current user. We access the REMOTE_USER
variable from the request.environ
dictionary, which contains all the environment variables set by the server.
Note that to access the REMOTE_USER
variable, you need to make sure that Apache is properly set up to perform authentication and pass the authenticated user's information to the Flask app. This typically involves configuring Apache with the appropriate authentication module (e.g., mod_auth_basic
) and enabling the CGI
option or setting up a WSGI
script for the Flask app.
Additionally, keep in mind that the availability of the REMOTE_USER
variable depends on the authentication mechanism used by Apache and the configuration of your server. If you are using a different authentication method or your Apache configuration is different, you may need to use other methods to obtain the current user's information.
